He is a member of the Shiranui
clan who has the blood of demons and follows the "way of darkness". He is considered the strongest warrior in his
clan by some, which has caused him to be extremely confident, declaring
himself a "king", when in reality he is just a minion amongst the
masses. He's also considered very handsome by his clan members as well.
Despite his bold proclamations for the sake of evil, Gen-An is mostly a
light-hearted character who just wants the best for his family.
In the first Samurai Shodown, he
believes that he should be the ruler of all demons and goes out to kill Amakusa.
He seeks to enlighten
his progress in the "way of evil". To this end, he travels Japan,
killing anyone he can. During his travels, he was killed by an unknown female ninja (very high chance
this is Ayame).
A year later (in Samurai Shodown 2), his
soul was revived by Mizuki, the leader
of the Demon World. He was
told that if he works for her, she would give him a second life. Although Gen-An
agreed, he planned to kill her any chance he got and take her place.
In his SS2 ending game, he is convinced by his wife, Azami, to return
home and live in peace. It
appears Gen-An also admires Haohmaru, as he is
seen parodying him during one of his win poses. Gen-An is also "rumored" to
Mai Shiranui's ancestor (although this
hasn't been proven).
